What I don't understand is, that if it's purely skin color and upbringing and background, why is most of SV absolutely dominated by Indian people: My dad is Indian and grew up with his family in a single room. He is in his 80s now and has a net worth in California of probably $3M. I'm half Indian and half white. At my age (42) he was doing way better than myself (accounting for inflation of course). When my dad was going through all the same stuff, 50 years back there was no affirmative action yet he still grew in the ranks. He's not a "black person" but his skin color is the same. I think there is a lot of perceived racism when in reality people are promoting strong individuals already. Look at head of Google, Twitter, and a series of other companies. For some reason people shy away from calling out racism when it comes to people from India because of their American success story. But again, if it's about skin color - how did this happen?
